Title:
AIR CLEANING SOUNDPROOF PANEL
Document Type and Number:
Japanese Patent JP3792081
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an air cleaning soundproof panel capable of reducing noise and NOx.
SOLUTION: An air layer 7 is provided at the back of a front face board 2 having a number of holes 21, and a coating film 9 containing a photocatalyser is formed on the front face plate 2. Air vent holes 8 communicating with the air layer 7 are formed on the upper plate 4 and/or the lower plate 5. NOx or the like in the air is removed by the coating film 9 containing a photocatalyser formed on thr front face plate 2. The air near the ground surface containing much NOx or the like stirred up by traveling vehicles does neither spring up nor stagnate near the front face plate 2 but flows in the soundproof panel 1 from the holes 21 of the front face plate 2 and passes through the air layer 7 and flows out from the vent holes 8 to the outside. Hence, polluted air including NOx is flows in sequence and gets into contact with the photocatalyser to extremely effectively remove NOx.
